On the homepage there are 2 links that are not https:
<a href="http://www.wolfesimonmedicalassociates.com/sildenafil-citrate/">http://www.wolfesimonmedicalassociates.com/sildenafil-citrate/</a>
<a href="http://advicarehealth.com/diflucan.html">http://advicarehealth.com/diflucan.html</a>
You either need to search the source code of each front-end page, identify the hardcoded http links, and then change them manually in the backend; or, do a find and replace in the database (http://advicarehealth.com >> https://advicarehealth.com). For the latter option, use a plugin like https://ww.wp.xz.cn/plugins/better-search-replace/ and backup the database before making any changes.
You will need to search and replace all the instances of the URLs in the database.
I’m coming in to also suggest a search/replace and provide some helpful articles for you.
Please check https://www.godaddy.com/help/find-and-replace-with-a-wordpress-plugin-26399 and https://www.godaddy.com/help/database-find-and-replace-26404 prior to performing this.
Hope these help!
